Wallace Bench Hardness Testers
Wallace offer both macro and micro bench-mounted instruments for evaluating the hardness of rubber and soft
plastics in two different measurement scales – IRHD and Shore. All of these robustly designed instruments conform
to international testing standards:
• H14 Macro IRHD Hardness Tester
• H12 Micro IRHD Hardness Tester
• H17A/C/D/O Macro Shore Hardness Tester
• H17M Micro Shore Hardness Tester
Versions
To suit customers’ varying needs and budgets, Wallace offer 4 versions of each bench-mounted model from
a basic, standalone version to a computer-linked version:
Hardness Tester - Basic Model
Features include:
• Touch button, automatic operation
• Visual LED indication of foot and indenter
contact
• Digital display with programmable resolution
to 0.1, 0.5 or 1 units
• Built-in diagnostics to check the instrument’s
internal settings
Hardness Tester - Basic Model with printer
The compact, high-speed, 24 character-width printer,
provides a permanent record of results and instrument
settings. Various parameters can be set including:
• Sample identification with auto-increasing suffix
• Date and time of test
• Traceability of aborted tests
Hardness Tester - Basic Model with printer
and Data Input Terminal
The data input terminal contains a 16 character, two-line
LCD display and QWERTY keypad. It supplies additional
information on the operation of the hardness tester and
offers the user several new options. Test parameters are
more easily set. Data for operator and sample
Identification can be entered. The timing of the primary
and secondary indenter loads (H12 and H14) can also be
pre set. Other features include:
• Data and time recording and traceability
• Calibration check reminder
Hardness Tester - Basic Model with PC Interface
This version provides a RS232C interface. Data is
transmitted at the end of a test, allowing a PC to
collect the results. An optional X23 add-in software
tool for Excel is available.

Hardness: H12 Micro IRHD Hardness Tester
The Wallace H12 is a digital bench-mounted hardness tester that measures in IRHD the hardness of most rubber samples. In particular it has been designed to accurately test thin sections and small test pieces such as O-rings. The robust, ‘C’ frame design allows the operator easy access from front and sides to safely load and remove
samples. The indenter mounting is essentially frictionless and its position sensed by a linear variable differential
transformer, providing the instrument with outstanding sensitivity. Adjustable anti-vibration feet reduce the effect
of external vibration.
By simply pressing the start button, the instrument functions automatically, allowing accurate, repeatable results
to be recorded in much less time than traditional models.
As minimal training is required, new operators soon become confident with the H12, achieving consistent
readings from the outset.
A range of optional sample tables is available, designed to locate samples of varying shapes and special
sample holding fixtures. It includes the O-ring adaptor (H19/ORA) that ensures the centre of the ring is directly
beneath the centre line of the indenter.
Keys on the front panel easily adjust the measuring head up and down to suit the sample height. Once the start
key is pressed, the foot descends to secure the sample, followed by the indenter, which lowers through the
centre of the foot with a primary force of 8.3mN to find its datum position. After 5 seconds, in line with the testing
standards, the force is increased to 153.3mN and applied for a further 30 seconds. At this point the instrument
identifies the indenter position and the hardness value is automatically frozen and displayed clearly on the LCD
screen.
The Wallace H12 Micro Hardness tester allows accurate and
repeatable measurements of small thin samples such as O rings.

The Wallace H14 is a digital, bench-mounted hardness tester designed for measuring in IRHD the hardness of
standard rubber samples.
The robust, ‘C’ frame design allows the operator easy access from front and sides to safely load and remove
samples. The indenter mounting is essentially frictionless and its position sensed by a linear variable differential
transformer, providing the instrument with outstanding sensitivity. The adjustable anti-vibration feet reduce the

Keys on the front panel easily adjust the measuring head up and down to suit the sample height.
Once the start key is pressed, the foot descends to secure the sample, followed by the indenter, which lowers

instrument identifies the indenter position and the hardness value is automatically frozen and displayed clearly on
the LCD screen. Two LEDs on the instrument’s front panel monitor all stages of the test cycle.

Hardness: H17 Shore Scale Hardness Tester
Features
• Tests soft and hard materials using different
scales
• One touch fully automatic operation
• Accurate and consistent results
• Easy access to sample area
• Operator dependency reduced
• Range of sample tables
• Four models offered
The Wallace range of H17 digital, bench-mounted hardness testers is designed for measuring in Shore scale the
hardness of various materials. Four models are offered – the H17A for testing standard rubber, H17O for soft
rubber and medium density textiles, H17D for hard rubbers and plastics and H17M for thin/small rubber samples.
The robust, ‘C’ frame design allows the operator easy access from front and sides to safely load and remove
samples. The adjustable anti- vibration feet reduce the effect of external vibration.
By simply pressing the start button, the instrument functions automatically, allowing accurate, repeatable results
to be recorded in much less time
than traditional models.
As minimal training is required, new operators soon become confident with the H17, achieving consistent
readings from the outset.
A range of optional sample tables is available, designed to locate samples of varying shapes, sizes and special
holding fixtures. Keys on the front panel easily adjust the measuring head up and down to suit the sample height.
Once the start key is pressed, the foot descends to secure the sample. In line with the testing standards, once
the foot contacts the sample the indentation depth is recorded after a pre set dwell time, typically 3 seconds.
At this point the instrument identifies the indenter position and the hardness value is automatically frozen
and displayed clearly on the LCD screen.
The Wallace H17 series of hardness testers allows accurate
measurement of both soft and hard materials using multiple
Shore Scales.

Hardness: Hardness Test Blocks
The test blocks are for use as a check to ensure instruments are functioning properly and read correctly.
They are not intended as standards with specific hardness values. Test blocks should be returned to Wallace
every 12 months for re-calibration. The table below lists the test blocks available.
Features:
• Manufactured from specially formulated high-quality rubber
• Resistant to ageing effects of temperature and time on hardness.
Wallace Rubber Hardness Test Blocks are available in five
scales – IRHD (Macro), IRHD (Micro), Shore A, D and M.
